Relationships between Piagetian cognitive development at the formal level and science background among prospective elementary school teachers

Creator:: Ehindero, Olusola Joseph
Abstract:: Results of recent studies on Piagetian cognitive development, though equivocal, showed that the architectonic of formal operational schemata is not possessed by a sizeable percentage (up to 52%) of adolescents and young adults. The purpose of the present study is two fold: (i) To assess the cognitive levels of a...

Prey selection by the tropical marine snail Thais melones : a study of the effects of interindividual variation and foraging experience on growth and gonad development

Creator:: West, Lani
Abstract:: I studied the feeding behavior of marked individuals of the carnivorous marine snail Thais melones in a rocky shore habitat of Pacific Panama. The population of snails consume a variety of invertebrate species such as bivalves, limpets, and polychaetes. Individuals exhibited a range of diet breadth, with some specialized, but...

The role of perinatal androgens in the development of neuroendocrine and behavioral characteristics of the gray-tailed vole, Microtus canicaudus

Creator:: Spielvogel, Sandra Petersen
Abstract:: These studies examined the role of perinatal androgen in the development of neuroendocrine and behavioral characteristics of gray-tailed voles, Microtus canicaudus. When mature, females exhibited alternating vaginal smear patterns or persistent vaginal cornification; estrogen and progesterone concentrations were not correlated with vaginal smear patterns. Corpora lutea were not observed in...

The progression of aflatoxin B₁ (AFB₁) hepatocarcinogenesis in rainbow trout (Oncorhynchus mykiss) : I. AFB₁ metabolism and cytotoxicity affecting hepatocarcinogenesis II. Ultrastructure of hepatocellular neoplasms

Creator:: Núñez, Oliva
Resource Type:: Masters Thesis

A lysozyme-like protein in the salivary glands of adult Aedes aegypti : functional and biochemical characteristics

Creator:: Pimentel, Gliceria Estandian, 1958-
Abstract:: This study investigated some functional and biochemical characteristics of a bacteriolytic protein in the salivary glands of adult Aedes aecupti. A method for the isolation of this protein from other mosquito salivary gland components is also described. Based on some of its biochemical properties, this bacteriolytic protein can be classified...

Investigation of the mechanism of 2,3,7,8-tetrachlorodibenzo-p-dioxin-induced immunotoxicity in C57B1/6 mice : effects on T cell activation

Creator:: Prell, Rodney A.
Resource Type:: Dissertation

Rainbow trout cystatin C : gene expression, heterologous production and characterization

Creator:: Li, Fugen
Abstract:: Rainbow trout cystatin C cDNA has been isolated from trout liver. The full-length cystatin cDNA (674 bp) included the 5'untranslated region and the polyadenylation signal sequence AATAAA in the 3' region. Translation of the cDNA defines 132 amino acid residues. Comparison of the amino acid sequence with those of family...

Involvement of inflammation and associated Mac-1⁺Gr-1⁺ cells in the immune suppression induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)

Creator:: Choi, Jin-Young, 1964
Abstract:: Exposure to TCDD suppresses the generation of immune responses through unknown mechanisms. Interestingly, TCDD enhances inflammatory responses to various stimuli. The goal of the studies presented in this thesis was to examine the role of hyperinflammation in TCDD-induced immunotoxicity. Previously we observed an increase in Mac-1⁺ cells in the spleen...

The effects of elevated temperature and stress on immune function in juvenile chinook salmon (Oncorhynchus tshawytscha)

Creator:: Harrahy, Laura Nicole Martini
Abstract:: Stress, including extreme or rapidly changing temperatures, are known to have deleterious effects on fish health and physiology. This thesis examines the combined effects of elevated acclimation temperature and acute handling stress on the number of antibody producing cells, plasma lysozyme concentrations, and the number of pronephric leukocytes in juvenile...

Characterization of an inhibitor ("6S") of infectious pancreatic necrosis virus (IPNV) in normal rainbow trout serum (RTS) and its effects on the virus

Creator:: Park, Kyoung Chul
Abstract:: The characteristics of an inhibitor of infectious pancreatic necrosis virus (IPNV) found in normal rainbow trout serum (RTS) were studied. The serum inhibitor had a molecular weight of approximately 150 kDa and was dependent on divalent cations, either Ca²⁺ or Mg²⁺. It was stable at temperatures up to 50°C and...
